I had thought about bundling for a while now but isn't it true that one connector will be supporting the weight of all the cables unless some other measure is taken to support them?

All cables should be fastened down on both ends as strain relief, before any of them go to a connector. Hard to see in this pic, but on both ends of the tether, all cables are tie wrapped down, before distributing to their terminations.http://www.pbase.com...048303/original

One element of my cable bundle is a hook that attaches to the camera independent of the electrical connectors. ALl the weight/strain is on that connector. It is hooked to an eyescrew (a little screw with a round head in the shape of an eyelet). The eyescrew connects to the "Tripod" connector on the bottom of the camers. This is a standard 1/4-20 screw hole.
